Bill Cosby's lawyers have outlined the tough questions the accuser likely will face now that their client is heading to trial in a criminal sexual-assault case.

The lawyers in a suburban Philadelphia court on Tuesday asked why accuser Andrea Constand stayed in touch with Cosby in the year after the 2004 encounter.

They suggested that she was instead in a consensual relationship with the man she considered a "trusted" friend and mentor.

The questions are similar to those raised by a former prosecutor who declined to arrest Cosby a decade ago.

Montgomery County District Attorney Kevin Steele believes there's new evidence to strengthen his case.

Cosby does not yet have a trial date. The 78-year-old faces up to 10 years in prison if convicted of aggravated sexual assault.
